PIR Motion Sensors PaPIRs Quick Digest

Passive InfraRed (PIR) sensors detect changes in infrared radiation which occur when there is movement by a person (or object) which is different in temperature from the surroundings. As this sensor detects temperature differences, it is well suited to detecting the motion of people by their body temperature.
Panasonic develops and produces PIR Motion sensors (PaPIRs), which combine easy integration, high reliability and environment-friendly materials.
